The Intelligence Index is a powerful way to separate big winners from big losers in the NFL and to consistently win games both straight up and, more importantly, against the spread.

The Intelligence Index is our way to identify which teams are the best in situational football. Smart, well-coached teams do all the little things right in all phases of the game: master third downs, win the turnover battle, dominate in the red zone and excel on special teams. Dumb teams consistently fail in all these situations.

We rank every team in Intelligence, from No. 1, the smartest team, to No. 32, the dumbest. Smart teams consistently win games both straight up and ATS; dumb teams consistently lose games both straight up and ATS.

Professor of Pigskin Jonathan Comey has identified 29 Mental Mismatches so far this season at CHFF Insider. That's when a smart team plays a dumb team. The smart teams are winning at an incredible clip of .862 straight up (25-4) and .667 against the spread (18-9-2).

The secret to the indicator's success is very simple: most folks look only at the physical qualities of each team. But we look also at their overlooked mental capabilities, too, which gives us a leg up on the marketplace. It turns out that the betting public consistently overvalues the physical capabillites of a team and undervalues their mental capabilities, as the 2013 Texans prove with startling clarity.

Put another way, the five smartest teams on the Intelligence Index are:

38-21-1 (.644) against the spread

44-16 (.733) overall

At the other end of the spectrum, the Jacksonville Jaguars and Houston Texans have filled the bottom spot in the Intelligence Index all season long. They boast the worst combined records straight up and ATS of any two teams in football.

Jacksonville and Houston are a combined 5-19 SU and 7-17 ATS. They're not alone. The five dumbest teams on the Intelligence Index are:

21-39 (.350) against the spread

17-43 (.283) overall

The Texans, No. 32 this week, are the poster child for the success of the Intelligence Index: They are No. 3 in total defense, No. 10 in total defense, and No. 7 in Total Team Yards Differential. In other words, Houston consistently wins the physical battles.

But the stupid Texans consistently lose the mental battles. They are No. 32 on the Intelligence Index, and just 2-10 overall and 3-9 ATS. Folks who examined Houston's mental incapacities have consistently won money this year knowing that they'd fail to come through despite their physical prowess.

The "smart" teams in our 29 Mental Mismatches this year are an incredible 25-4 straight up and a sterling 18-9-2 ATS (.667).

There are few if any folks in football pitching ATS winners with 2 out of 3 picks over the course of an entire season. But we are with the Intelligence Index, and we document every single pick and every single result each week at CHFF Insider.

Perhaps most impressively, the smart teams consistently win in blowout fashion. The smart teams have been favored in all 29 of our Mental Mismatches, and by an average of 5.3 points.
